FLAxseED-CLEANER.

SPECIFICATION forming part of Letters Patent No. 248,693, dated October25, 1881.

Application nien May 12,1881. (Model.) i

To all whom it may concern:

Be it known that I, GEORGE BEAL, of Gilman, Marshall county, Iowa, haveinvented a new and Improved FlaXseed-Gleaner, ot' which the following isa specitication.

The object of my invention is to provide a machine which will thoroughlyseparate aX- seed from the chaff', screenings, and other impurities andproduce a clean and pure product.

In the accompanying drawings, Figure lis a plan view of my invention.Fig. 2 in a longitudinal section taken on line x x, Fig. l; and Fig. 3is a cross-section taken on the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

.The screen A is suspended from the upper cross-bars of the frame innearly a horizontal position within the boxB, which boX is secured to orformedin the frame, which latter is composed of the uprights G, uppercross-bars, D D', horizontal bars F F,lower cross-bars, E and E', thecross-bar E being elevated, as shown, to support the joined ends of theinclined bottom boards, d d, ot' the box. Thelinks a o, by which thescreen is suspended from the upper crossbars, D', pass through thecross-bars GG, which are secured to the frame ofthe screen near the endsthereof, and the links are provided above the cross-bars D and below thebars G G with suitable screw-nuts for regulating the slant ot" thescreen; and between the cross-bars Dl D and G G are placed the springs gg at the four corners of the screen, which hold the screen firmlyagainst any vertical movement which would cause an undesirablejumpingaction to be given to the grain. In someinstances blocks of Woodmay be used in place of the springs.

Longitudinally across the centerof the screen, and secured at its endsto the centers ot the cross-pieces G G, is thebar H, through whichmotion is imparted to the screen by means of the wiper-Wheel K andangle-lever L (thelower end ofwhich lever is pivoted in a slot in thebar H) and the spring N, which is placed upon and secured to the bentrod n, screwed to the bar,

and the rod n', which passes through the crosshead y', which abutsagainst the outside of the uprights C C at the end ot' the frame. The

To the side ofthe cross-bar D is secured the' horizontal bifurcated armQ, in which the lever L is fulcrumed. The upper end of this lever isheld against lateral movement from frictional contact with the wheel Kby the rod q, which is secured to the lever and to the eye c on thecross-piece D, as shown, and the upper end of the lever is held inconstant contact with the wiper-wheel by the action ofthe spring N, sothat upon motion being imparted to the Wheel K the projections thereonwill give to the screen sudden and rapid longitudinal jerking andshaking movements.

In order to obviate any jarring action due to too sudden stopping of thescreen, which would cause the screen to throw up or toss the grain, Iprovide the spring or rubber (preferably rubber) bumpers it', which areplaced in holes through the blocks t t, -secured to the sides of thebox, so as to nearly come in contact with the projections t t', securedto upper edges ot' the screen-frame, as shown. These springs or rubberbumpers are adjustable in the blocks by means of the rods c' e', whichscrew into the blocks for the purpose of regulating the action of thescreen, and also for regulating the feed ofthe grain from the mouthofthe hopper M, which is held in close proximity to the screen.

The hopper is supported in a board or plate placed upon the cross-piecesDl and Dll and near the forward end of the screen. That portion of thescreen c which is near the hopper is of perforated sheet metal, whilethe screens c c are of woven wire.

In operation, the seeds to be cleaned being fed to the hopper and motiongiven to the wheel K by any power applied to the crank or pulley, thescreen will be given a rapid, sudden, but still an. easy longitudinalback-and-forward motion, which will cause the small seedssuch as mustardand foXtail seeds-and the other small impurities to pass out the openingIt of the box, and cause the material to slowly traverse the screens,the screenings and the other impurities passing out the spout Sof thescreenframe, the pure flaxseed passing out at the opening R of the box.

It will be understood that a body of the material being separated willbe maintained upon the screens or sieves. By adjusting the rubberbumpers the depth ot' this body can be regulated-that is to say, byforcing the rubber farther out of the blocks the discharge of screeningswill, as the rearward impulse of the screen is retarded a greaterdistance, not be so rapid, and by withdrawing the screws the dischargewill be more rapid.

The rapidity of the feed from the hopper will always be in accordancewith that of the discharge. The rearward movement of the screen issomewhat retarded by the rubber bumper, while the forward movement isnot retarded. This slow rearward and sudden forward motion tends tomaintain a body of material upon the screen, which banks around thedischarge-pipe from the hopper and prevents the flow ot material, exceptas fast as the same passes oi' from the screen; so a uniform depth ofthe material upon the screen can be accurately maintained, which is ofgreat advantage.

Though I have described my invention as applicable for cleaningtlaxseed, it is obvious that by changing the screen to suit it can beused for cleaning other seeds and grain with equal eficency.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the screen A, of thelever Land wiper-wheel K, the latter arranged in a plane at right angles to thehorizontal part of said lever, as shown and described, wbereby thescreen is given a peculiar lateral as well as a longitudinal movement.

2. The rod q, the wiper-wheel K, and spring N, combined with the leverL, to bold the latter in contact with the wiper-wheel without allowingany lateral movement to said lever, as described. l
